LightHawk™ Passive Infrared dual circuit wall switch sensor featuring IntelliDAPT®. IntelliDAPT self-adaptive technology, no manual adjustment required. 2 relays for either two-level switching or dual-circuit control. Auto-on and manual-on operating modes (depending on model). 1,000 square-foot, 180° coverage area. Built-in photocell with SuperSaver™ mode. RhinoTuff™ lens. Dual 120/277 or 347 VAC operation. No minimum load requirement. Zero arc point switching. ETL, UL, and cUL listed. California Title 24 compliant. LHIRD sensors use passive infrared (PIR) technology for unequaled occupancy detection and false trip immunity. The sensors, designed for dual-level lighting applications, possess 2 primary circuits (each with independent switching). LHIRD sensors feature Hubbell Building Automation’s patented IntelliDAPT technology, which makes all the sensor adjustment decisions automatically. Throughout the product’s lifespan, smart software analyzes the controlled area and makes digital adjustments to sensitivity and timer settings. Occupancy sensors with IntelliDAPT provide a maintenance-free install-and-forget operation. With selectable operating modes automatic ON/OFF or manual ON/automatic OFF and a built-in photosensor for automatic daylight harvesting.
